The purpose of this study is to analyze the energy consumption characteristics of single-person household complexes and 3-4-person households. Specifically, in order to minimize the effect of the difference in household size and number of residences, the actual energy consumption was processed into dimensionless numbers to check the consumption type and measure the similarity. The conclusions obtained from this study are summarized as follows: (1) First of all, this study proposed a dimensionless processing of energy consumption to minimize physical differences between comparison targets. Through this, it was possible to analyze the characteristics of energy consumption by time scale regardless of the difference in size and number of households, but it was confirmed that there was a limit to implementing the actual consumption characteristic. (2) As a result of the analysis of energy consumption characteristics, single-person households showed a difference in the daily consumption change of households with 3-4, which means that the characteristics of the simultaneous use rate and base load are different. In particular, by time scale, the fluctuation in consumption of single-person households tended to be large, and the time scale during which maximum consumption occurred was also relatively large compared to general households. (3) The similarity of the type of heating consumption was calculated 50.8% .Which means that the effect of the difference in the number of household members was relatively small. However, the consumption of power and hot water consumption were 7.1% and 7.8%, respectively, and it was analyzed that the consumption characteristics of single-person households and households with 3-4 people differed significantly.
